AI: World likely to hit key warming threshold in 10-12 years

Baku, January 31, AZERTAC
The world will likely breach the internationally agreed-upon climate change threshold in about a decade, and keep heating to break through a next warming limit around mid-century even with big pollution cuts, artificial intelligence predicts in a new study that’s more pessimistic than previous modeling, according to AP.
The study in Monday’s journal Proceedings of the National Academy of Sciences reignites a debate on whether it’s still possible to limit global warming to 1.5 degrees Celsius, as called for in the 2015 Paris climate agreement, to minimize the most damaging effects of climate change. The world has already warmed 1.1 or 1.2 degrees since pre-industrial times, or the mid-19th century, scientists say.
Two climate scientists using machine learning calculated that Earth will surpass the 1.5 degree (2.7 degrees Fahrenheit) mark between 2033 and 2035. Their results fit with other, more conventional methods of predicting when Earth will break the mark, though with a bit more precision.
In a high-pollution scenario, the AI calculated, the world would hit the 2-degree mark around 2050. Lower pollution could stave that off until 2054, the machine learning calculated.
In contrast, the United Nations’ Intergovernmental Panel on Climate Change figured in its 2021 report that the same lower-pollution scenario would see the world pushing past 2 degrees sometime in the 2090s.
